I redid the following:
import os
import sys
sys.path.append('C:\Program Files\EPANET2')
os.system('epanet2d.exe C:\simulation_test\Network3_1.inp C:\simulation_test\Network3_1.out')
import sys
sys.path.append('C:\Program Files\EPANET2')
os.system('epanet2d.exe C:\simulation_test\Network3_1.inp C:\simulation_test\Network3_1.out')
and safed this as test.py
In the Pythonwin interface to run. I got nothing.
Then I added 'C:\Program Files\EPANET2' into the system path.
In the cmd line: I typed python c:\test.py. It ran and then gave the output.
Don' t know why command line works. but pythonwin interface failed .
Thanks.

Any non zero return value means that an error occurred.
The os.system call worked and the OS returned an error, which
usually means you got a path wrong or the user running puython
doesn't have access rights to the executable.

What happens if you try it from the Start->Run dialog?
The CMD box may have some environment settings that are missing
when Python runs.
